Caught on camera !

This year we planned camera-trapping (left) and photos by trigger-happy photographs (below) to increase recapture rate. 
Both methods resulted in additional readings to those made by telescope alone. After these encouraging results we will be probably using these techniques regularly. A special thanks to Miguel, Javi y Paco for the nice images.

New Publication on rewilding !

Perino, A., Pereira, H.M., [..], Cortés-Avizanda,A.,[...] and Wheeler, H.C., 2019. Rewilding complex ecosystems. Science 364, DOI: 10.1126/science.aav5570 

Abstract: The practice of rewilding has been both promoted and criticized in recent years. Benefits include flexibility to react to environmental change and the promotion of opportunities for society to reconnect with nature. Criticisms include the lack of a clear conceptualization of rewilding, insufficient knowledge about possible outcomes, and the perception that rewilding excludes people from landscapes. Here, we present a framework for rewilding that addresses these concerns. We suggest that rewilding efforts should target trophic complexity, natural disturbances, and dispersal as interacting processes that can improve ecosystem resilience and maintain biodiversity. We propose a structured approach to rewilding projects that includes assessment of the contributions of nature to people and the social-ecological constraints on restoration. 

New publication on Red Kite in Doñana National Park !

Sergio F, Tanferna A, Chicano J, Blas J, Tavecchia G, Hiraldo F. 2019 Protected areas under pressure: decline, redistribution, local eradication and projected extinction of a threatened predator, the red kite, in Doñana National Park, Spain Endangered Species Research. 38: 189-204

Abstract: After a period of overfocus on reserve establishment, growing attention is being devoted to the capability of protected areas to maintain viable populations of endangered species. Here, we examined the trends and reproduction of the red kite Milvus milvus, a highly endangered raptor near-endemic to Europe, to illustrate the dual benefits and challenges faced by a national park to protect this iconic species. Over the past 4 decades, the kite population of southern Spain has declined steeply and become progressively confined to Doñana National Park and its buffering Natural Park. Population deterioration was also evident within the protected area through (1) spikes of rapid eradication of whole sub-populations from buffer areas, likely propelled by illegal poisoning, and (2) more gradual but steady deterioration of numbers and reproduction, especially in peripheral-buffer areas, probably caused by the interplay of several shocks related to food availability, habitat degradation, competition, predation, and chemical contamination. The result was a 46–55% decline with progressive confinement to the core National Park and an alarming effective population size <10 pairs. Demographic modelling suggested low adult survival and predicted further declines, with possible extinction over the next 2 decades. We outline tentative goals for management, but these will need urgent information on ranging and mortality to provide more efficient targets. These results illustrate how establishment of a large park can prevent regional extinction, but not necessarily guarantee species-safety, leading to protracted forms of extinction debt. We suspect that similar dynamics will become more widespread as anthropogenic pressures increase around protected areas and their performance-monitoring becomes more prevalent.

Yellow-Legged Gull campaign 2019!

Yellow-legged gull campaign on the starting blocks! It will be our 13th year and looking forward to see how the gulls did this year.

M. Martin Perez and M. Castell from the University of the Blearic Island, and A. Sola from the University of Santiago began their Final Work (TFM) for their Master Degree on Marine Ecology with the GEDA.

M. Castell

 Maria will be focussing her research on the response of Cory's Shearwater to climatic changes, Marga will experimentally evaluate the recruitment behaviour of Storm Petrel and Alfonso will study the foraging strategy of the Yellow-Legged Gull. They will be supervised by A. Sanz-Aguilar, G. Tavecchia and J.-M. Igual.
Their respective fieldwork campaigns are on the starting blocks !

New Publication on Petrels and Shearwaters: where are we and where to go

Rodriguez, A, [...] Sanz-Aguilar, A. et al. 2019. Future Directions in Conservation Research on Petrels and Shearwaters. Frontiers in Marine Science. https://doi.org/10.3389/fmars.2019.00094

Abstract: Shearwaters and petrels (hereafter petrels) are highly adapted seabirds that occur across all the world’s oceans. Petrels are a threatened seabird group comprising 124 species. They have bet-hedging life histories typified by extended chick rearing periods, low fecundity, high adult survival, strong philopatry, monogamy and long-term mate fidelity and are thus vulnerable to change.

Anthropogenic alterations on land and at sea have led to a poor conservation status of many petrels with 52 (42%) threatened species based on IUCN criteria and 65 (52%) suffering population declines. Some species are well-studied, even being used as bioindicators of ocean health, yet for others there are major knowledge gaps regarding their breeding grounds, migratory areas or other key aspects of their biology and ecology. 

We assembled 38 petrel conservation researchers to summarize information regarding the most important threats according to the IUCN Red List of threatened species to identify knowledge gaps that must be filled to improve conservation and management of petrels. We highlight research advances on the main threats for petrels (invasive species at breeding grounds, bycatch, overfishing, light pollution, climate change, and pollution). We propose an ambitious goal to reverse at least some of these six main threats, through active efforts such as restoring island habitats (e.g., invasive species removal, control and prevention), improving policies and regulations at global and regional levels, and engaging local communities in conservation efforts.
